          A soft commit is much faster since it only makes index changes visible and does not fsync index files or write a new index descriptor. 
          If the JVM crashes or there is a loss of power, changes that occurred after the last hard commit will be lost. 
          Search collections that have near-real-time requirements (that want index changes to be quickly visible to searches) will want to soft commit often but hard commit less frequently.
